The SDA 18000/13000/11000/9000 oscilloscopes achieve higher bandwidth and sample rate
using an innovative LeCroy technology called Digital Bandwidth Interleaving (DBI). This
technology allows resources to be borrowed from unused channels to multiply not only sample
rate but also bandwidth.

When 18 GHz is selected, the active channels are either C1 or C4
or both, providing 60 GS/s sampling on the 18 GHz channel, and
20 GS/s sampling on the 6 GHz channel.
When 18 GHz is selected, the active channels are either C1 or C4
or both, providing 60 GS/s sampling on the 18 GHz channel, and
20 GS/s sampling on the 6 GHz channel.
When 11 GHz is selected, the active channels are C1, C3 and C4.
The 11 GHz channel provides 40 GS/s sampling, while the 6 GHz
channels provide 20 GS/s sampling.
When 11 GHz is selected, the active channels are C1, C3 and C4.
The 11 GHz channel provides 40 GS/s sampling, while the 6 GHz
channels provide 20 GS/s sampling.
When 6 GHz is selected, all 4 channels are active, each providing
20 GS/s.
When 6 GHz is selected, all 4 channels are active, each providing
20 GS/s.

When 13/11/9 GHz is selected, the active channels are either C2 or
C3 or both, providing 40 GS/s sampling on each channel. For 6
GHz bandwidth, all four channels can be used, providing 20 GS/s
sampling on each channel. Channels can be set to allow 13/11/9
GHz and 6 GHz bandwidths at the same time, as shown at left.
